Title: Hose couplings
Inventor: CANNON DAVID WILLIAM CHARLES
IPC: F16L17/025
Filed: 1990-07-09
Abstract: In a hose (1) and hollow member (2) arrangement in which the hose is fittable at its end over the hollow member, the hose (1) has an annular recess (3) for receiving an annular projection (10) of the hollow member, and beyond this recess (3) in the direction away from the end of the hose a lip seal (4) extending all around the inner wall of the hose for engaging the end face of the hollow member (2) with a gap (9) left between the opposing faces of the inner wall of the hose (1) and the lip seal (4). When assembled, a fastener (12) secured around the end portion of the hose (1) holds the hose fast against the hollow member (2) neared to the end of the hose than the recess (3) so that the radial securing force does not act on the lip seal (4) which is therefore unaffected by this securing force. It is the lip seal (4) that seals against internal pressure that acts on the lip seal to reinforce the sealing action of this seal. <IMAGE>

Title: Mixing dry polymer and electrolyte
Inventor: PARDIKES DENNIS GEORGE
IPC: C02F1/52
Filed: 1991-09-27
Abstract: A system for thoroughly wetting a dry polymer and mixing it with water, or another electrolyte, uses a funnel 34 in which dry polymer mixes with swirling water, the funnel spout 50 opening directly into the vortex 52 of a centrifugal pump 42 which imparts substantial energy to the mixture. The mixture is then transferred to a mixing vessel 84 where a large volume of air is blown (86) through the mixture at a relatively low pressure while the mixture ages and hydrates. The viscosity of the mixture is enhanced by the conformationally structuring of the polymer at the water/air interface. <IMAGE>

Title: Electricity supply control systems
Inventor: BRADBEER RUSSELL
IPC: H01H47/00
Filed: 1993-06-30
Abstract: An electricity supply control system including a contactor 28, in particular a prepayment electricity meter 12 or a radio teleswitch, is provided with a circuit 30 for detecting the presence of the elecricity supply down-circuit of the contactor. If the supply is detected at a time when the contactor is supposed to be open, indicating for example that the contactor has welded shut or been bypassed, the circuit sends several pairs of control signals to the contactor, each pair tending to close the contactor and immediately re-open it, since such pairs of signals have been found effective in breaking the weld if the contactor has indeed welded shut. Additionally, a signal indicative of the detection of the supply when the contactor is supposed to be open is stored, in case it is indicative of an attempt to defraud the system. <IMAGE>
